    This channel is the reason i got 98/100 in Basic Calc. Amost all STEM students in my school relies on your videos. Keep it going!

      I think 99% of schools may just adopt this program and get more successful in teaching

    Six minutes in, as I drink some wine, I'm genuinely wondering why the hell I'm required to take Calculus. It has nothing to do with my major, and I seriously doubt anyone uses this stuff other than NASA scientists.
    **sigh**

    Would this be the same as cot(x) then? If so, why is it left as just (1/sinx)*cosx?

      It was probably left unsimplified like that so it wouldn't distract from the main point.

    I thought the derivative of ln(u) was u'/u so couldn't you use that to get cos(x)/sin(x)?

    OK. Perhaps one should mention your result as written are diff. coeffs, without a terminal dx.

    I just googled a picture of Sal Khan, and he's nothing like I imagined him to be. I pictured a generic white man from Texas with short brown hair

    2:45 " we have to take the derivative of outer function with respect to inner function"
    Actually that is not true,
    The outer function is ln(x), and inner function is sin(x), if what you said were true then it would be d/dx (ln(x)÷sin(x)) which is complicated.
    Actually the first part of the answer would be ' derivative of the whole function with respect to the inner function.'
    i.e., d/dx (ln(sin(x))÷sin(x)

    • @isavenewspapers8890
      @isavenewspapers8890 Před 8 měsíci

      The outer function is ln(sin(x)), and the inner function is sin(x). So if we take the derivative of the outer function with respect to the inner function, we have d/dsin(x) ln(sin(x)), which is 1/sin(x).
      What you have written, d/dx (ln(x)/sin(x)), is not the derivative of the outer function with respect to the inner function; it is the derivative of the quotient of two functions with respect to x. This is not what was said in the video.
